SAMUEL K. DENNIS, OF CHICAGO, ILLINOIS, ASSIGNOR '10 INTERNATIONAL HAR- VESTER COMPANY, A CORPORATION OF NEW JERSEY.

CORN-PLANTER.

noemer.

To all whom it may concern:

Be it known that I, Santuari K. DnNNis, a citizen of the United States, residing at Chicago, in the county oit Cook and State oitl Illinois, have invented certain new and useful Iinprovements in Corn-Planters, ot which the following is a specification.

My :invention relates to corn planters, and in particular to thc means tor holding the bottom of the seed hopper in place when it is desired to turn the hopper about its hinge connection with its support` for the purpose of changing the seed plates or removing the seed from the hopper', and consists in an automatically operative locking mechanism that prevents the removal ol the bottom until the hopper has been turned about its hinge connection to a predetermined angle with its supporti; the object of my invention being to provide a mechanism simple and strong in construction and etiicient in operation. I attain these objects by means of the mechanism illustrated by the aecon'ipanying drawing, in which- Figure l represents a side elevation ot part oit a corn planter having my invention embodied in its construction; Fig. Q is a View of the bottom of the hopper on an enlarged scale; Fig. a side elevation ot part ot' Fig. l, representing thc hopper in various positions ot its swinging movement about the axis oit' its hinge connection with its support; and Fig. 4t is a similar view, partly in section, designed to illustrate the operation of the associated mechanism.

Like reference characters designate the same parts throughout the several views.

l represents a furrow opener oit' a corn planter having its rear end secured to the lower end ot a seed conduit 2, the upper end ot the conduit being provided with a forwardly projecting bracket portion 3 to which is secured a bar 4l :forming part of the draft trame of the machine.

5 represents a seed hopper supporting base secured to the upper side ot the bracket portion and having a seed shat't t5 journaled therein that is adapted to transmit rotary movement to a gear wheel 7 supported upon the hopper supporting base.

8 represents a seed hopper including a hinged lid 9 having a common form oi. locking mechanism 10, and 11 represents an annular ring that is connected with the hopper supporting base 5 by means of a hinge Specification of Letters Patent.

pin 12 and adapted to receive the lower end ot the seed hopper in a releasable manner, and 13 represents an outwardly projecting slotted ear portion oppositie the hinge pin that is adapted to receive a swinging loek ing member jl-'t pivotally connected with the supporting base member and adapted to secure the hopper and base member in operative relation in a well-known manner.

15 represents an annular plate provided with ear members '1,6 that have slotted openings therein that receive the hinge pin 19. in a manner permitting the plate to have a sliding movement relative to the annular ring A1l as the hopper is turned about its hinge connection.

17 represents a flange upon the hinge member ot the hopper supporting base that is arranged eccentric to the axis oit the hinge connection and adapted to contact with the edge o't` plate '15 in a manner to cause it; to slide upon the ring 11 when the hopper is turned to a closing position. As the ring slides away trom the hinge pin its opposite edge passes between an inwardly project-ing lip portion YIS integral with the ear portion lil and the bottom ot the ring l1 in a manw ner to lock the parts together, and when the hopper is turned to the position shown by dotted lines in `Fig. l the plate may slide away :trom the holding lip in a manner permitting it to swing independently of the ring ll and allow the removal ot' the seed plate 1f) and other operative parts of the seed delivering mechanism.

What I claim as my invention, and de sire to secure by Letters Patent, is:

'1. :lt corn planter including, in combination, a seed conduit, a seed hopper including a bottom plate, a hopper supporting base eonneiictial with said seed conduit, said hopv per being connected with said base by means ot' a hinge joint, said bottom plate being hingedly connected with said base eoaxially with said hopper and adapted to slide toward or trom the axis ot said hinge conneetion.

2. A corn planter including, in combina tion, a seed conduit, a seed hopper ineluding a bottom plate, a hopper supporting base connected with said seed conduit, said hopper being connected with said base by means ot a hinge joint, said bottom plate being hingedtrY connected with said base eoaxially with said hopper, and means operative to slide said plate away from the axis of said hinge connection toward the opposite side of said hopper when said hopper is turned about its hinge connection in one direction.

3. A corn planter including, in combination, a seed conduit, a seed hopper including a bottom plate, a hopper supporting base connected With said Seed conduit, said hopper being connected With said base by ineans of a hinge joint, said bottom plate being hingedly connected with said base coaxially With said hopper, and a ilange forming part of said hopper supporting base, said flange being arranged eccentric to the axis of said hinge connection and operative to slide said plate away from the axis thereof and to- Ward the opposite side of said hopper when said hopper is turned about its hinge connection in one direction.

4L. A corn planter including, in combination, a seed conduit, a seed hopper ineluding a bottom plate, a hopper supporting base connected With said seed conduit, said hopper being connected with said base by means of a hinge joint, said bottoni plate being hingedly connected With said base coaXially With said hopper, a liange forming part. of said hopper supporting base, said A iiange being arranged eccentric to the aXis of said hinge connection and operative to slide said plate away from the aXis thereof and toward the opposite side of said hopper When said hopper is turned about its hinge connection in one direction, and a lip portion forming part of said hopper and adapted to engage With said plate in a manner to hold it in contact With said hopper When said hopper is being turned in a reverse direetion.
